On a geometric approach to the estimation of interpolation projectors by Mikhail V. Nevskii, Alexey Y. Ukhalov

“…Here $\sigma S$ is the result of homothety of $S$ with respect to the center of gravity with coefficient $\sigma$. Let $d\geqslant n+1,$ $\varphi_1(x),\ldots,\varphi_d(x)$ be linearly independent monomials in $n$ variables, and $\varphi_1(x)\equiv 1,$ $\varphi_2(x)=x_1,\ \ldots, \varphi_{n+1}(x)=x_n.$ Put $\Pi:=$lin$(\varphi_1,\ldots,\varphi_d).$ The interpolation projector $P: C(\Omega)\to \Pi$ with a set of nodes $x^{(1)},\ldots, x^{(d)} \in \Omega$ is defined by equalities $Pf\left(x^{(j)}\right)=f\left(x^{(j)}\right).$ Denote by $\|P\|_{\Omega}$ the norm of $P$ as an operator from $C(\Omega)$ to $C(\Omega)$ . …”

Multi-energy storage SoC equilibrium strategy based on the variable regulating factor by CHEN Jingwen, LIU Jiaxin, ZHANG Wenqian

“…In view of the overcharge and over-discharge of individual energy storage units due to differences in the state of charge (SoC), rated capacity and line impedance of the microgrid multi-energy storage units, which will affect its service life and make the stability adjustment ability of the microgrid deteriorate, this paper proposes a multi-energy storage SoC dynamic balance strategy based on the variable regulating factor. The arccotangent function is used to associate the droop coefficient with SoC and rated capacity, and the virtual voltage drop compensation link is introduced to achieve the balance of multiple sets of energy storage SoC. …”
